Brazil’s capital city of Rio De Janeiro(里约热内卢) is one of the cities in real danger of getting swallowed up by the rising waters, and the population of 1.8 million knows it. Research says that just an increase of 3 degrees Celsius could flood and envelop the Copacabana Beach, even a town nearby and the place’s airport.

Hi, this is Zak. See you again! Cindy and I had a secret conversation in the dream. We talked about the happiest days and both long for the better future of our planet. I died but I hope my family members can have a better life. So please help us!
Thinking:
Please think about what we can do to protect our planet with the current situation-Global Warming.




Walk or take public transport，not drive or reduce to drive cars.
Plant more trees, protect forests, not cut down or destroy trees.
Improve the technology of using energy, develop and adapt new clear energy.
Save energy by reducing to use plastic bags, choose and reuse energy-efficient products
Share your knowledge and educate more people to know the importance of protecting the earth.
Discuss and think: what you will do to help protect the earth?
Earth provides enough to
satisfy every man's needs,
but not every man's greed.

------Mohandas K. Gandhi
